17:41 < jenders> cjwatson: does the following mechanism for gating updates sound about right:
17:41 < jenders> You need to create a full mirror of the repository at a given point in time. Aim /etc/apt/sources.list for all hosts at this mirror and then sudo apt-get update && sudo apt-get upgrade
                 on each host. To perform updates you would need to update the full mirror while keeping a backup of previous versions in the mirror, probably with rsync without --delete. The repo
                 metadata would probably also need to be updated to include both new and older versions.
17:41 < jenders> and then pinning could be done either at the host level or by removing a .deb from the repo?
17:42 < cjwatson> rsync without --delete - not enough if you want clients to be able to stick at older point releases, you'd need to create new dists/ trees
17:43 < cjwatson> ah, maybe that's part of what got cut off by the IRC line length limit
